Promising to put a “real talk” spin on standard nutrition information, dietician Paula Norris isn’t one to sugarcoat—especially when it comes to calorie counting. In an eye-opening, ongoing series of photos, Norris asks her Instagram followers to “spot the difference” between high and low calorie meals.

In each picture, Norris presents a side-by-side look at pairs of seemingly healthy plates of food. While they often look nearly identical to one another, a closer look at the servings reveals their subtle differences, from portion size to protein amount. To illustrate the big impact of these small changes, Norris has labeled each dish with with the number of calories it contains, proving the big power of tiny tweaks.

According to Norris, it is these minor adjustments that make all the difference. “Green powders, juice detoxes, Paleo and blood type diets–unfortunately they’ve been shoved in our faces making healthy eating unnecessarily complicated,” she writes on MintFit. “The focus needs to be on smaller, sustainable dietary changes.” In order to help you make these changes, Norris adds detailed captions to each post, ensuring that her approach to calorie counting is crystal clear.
